x86: devicetree: re-enable x86-specific implementation

Fixing x86-specific DT implementation in the kernel allows reusing most of firmware code for SoC that have ARM core replaced with x86, e.g. SC9853i.

Changes since first version:

 * Splitting a single patch into three parts

Ivan Gorinov (3):
  x86: devicetree: call early_init_dt_verify()
  x86: devicetree: enable multiprocessing in DT
  x86: devicetree: fix device IRQ settings in DT
